I don’t really see it. Amazon techies wouldn’t have much in common with Amazon warehouse workers, and I’m not seeing any other people they could share solidarity with. But think if you are an SWE say at a traditional manufacturer, your needs and interested are going to differ a lot from someone working the assembly line.
The people making 200k a year are still workers. They may have savings and insurance that make them feel more secure, but they still need to clock in every day to afford to be alive. Their activities in their day to day life are constrained by "will Amazon fire me for this". If they ever suffer some kind of injury that prevents them from doing their day job they would quickly discover that their position is just as precarious as the delivery driver who brings them their cheap plastic shit from China.
